# Slope-intercept form
y = mx + b
with m stands for the slope, b stands for the y-intercept
# Given from the question
m = -6
y-intercept = 3 ((0,3) means that the y-intercept is equal to 3)
# Solution: substitute the information to the slope-intercept form
y = mx + b
y = -6x + 3
The equation of the line is y = -6x + 3
